IBM, in 1981. There was no specific invention or inventor of a first motherboard. The concept of a motherboard evolved over a number of years responding to the reduction in electronic component size. One of the original concepts in computer construction was the backplane. The backplane allowed for circuit card to be plugged in on one side. Its back had rows of pins corresponding to the socket connections. The pin connections defined how the attached circuit cards functioned and pins were connected to other pins with wires wrapped around them. As technology matured, electronic parts were combined into Integrated circuit (IC) chips which were mounted on the backplane itself and the pins and wiring on the rear of the backplane were replaced by printed circuits. This eventually became what we call a motherboard, mainboard or some equivalent name. Original microcomputers and personal computers had a central processor (CPU), memory, and control circuitry on the motherboard. That took up all the available space. Most other parts required their own support circuitry that would not fit on the motherboard so they were placed on individual circuit cards plugged into the motherboard. This included additional memory, output display, hard drives controllers, and even standard input/output ports such as serial (RS232,) Printer(parallel), mouse and game ports. Most of these eventually became compact enough to be integrated onto the motherboard board we use today.
A backplane is similar in concept to a motherboard, except it contains no significant electronics (i.e. all of the electronics components are on boards that plug into connectors on the backplane), a motherboard usually contains significant amounts of electronics components and may or may not have several connectors connected similar to those on a backplane for optional boards that could add functionality to the machine desired by the user. Some backplanes are not wired with all the connectors in parallel, but instead are wired "randomly" because every board plugged into the backplane has a specific purpose in the machine. These backplanes may not use any form of computer bus (e.g. address bus, data bus, control bus) or such buses may only be used to interconnect different backplanes within the machine or peripherals connected to the machine. Backplanes have been constructed using hand soldering of the connector pins, wire wrapping of the connector pins (either by hand or automated machine), printed circuit board (either flexible or rigid), etc.
The motherboard is main part of CPU. All parts do connect with motherboard.
The Mini ITX motherboard is only used within one computer system. It is used for small form factor or SFF computer systems. It enables an infinite development amount of SFF computer systems.

yes it is possible to use DDR800 on DDR667 motherboard. But to be certain please check you motherboard spec.
Early computers were entirely point to point wired either with soldered or wire wrapped connections. They usually used circuit modules that plugged into connectors mounted on the mainframe rack to make repair faster (when a problem was located the defective module could be quickly unplugged and a good module plugged in it's place to get the computer running again while the defective module was being repaired on the test bench). In the 1950s printed circuit boards replaced the point to point wired circuit modules, but the connectors they plugged into were still point to point wired together with soldered or wire wrapped connections. Starting with some of the minicomputers in the 1960s large multilayer printed circuit boards with the connectors for the individual circuit boards mounted on this large board. These large multilayer printed circuit boards were called "backplanes" and the connectors mounted on them "backplane connectors". These minicomputers might have several backplanes usually mounted in different sections of the rack containing the minicomputer (the rack was often larger than the size that was practical to make the backplane circuit boards). The first microcomputers in the 1970s copied minicomputers and used a single backplane (their chassis were small enough that usually one backplane was all that was needed). Beginning with the IBM PC in the 1980s "motherboards" replaced "backplanes", the motherboard contains much of the circuitry of the computer itself and connectors for the "daughterboards" while a backplane only contained connectors. No modern computers use backplanes or backplane connectors today, they are obsolete.
Depends on what your goals are for the motherboard, cost factor, preference, and time of purchase.
that is true
Which action is recommended to prevent the motherboard from contacting the metal base of the case? Ensure that the non-conductive side of the case is beneath the motherboard. Use standoffs to keep the motherboard above the metal base. Place a non-conductive barrier between the motherboard and the metal base. Use a self-adhesive non-conductive membrane on the underside of the motherboard. Which action is recommended to prevent the motherboard from contacting the metal base of the case?
